Figure 2. Various electrospinning setups used to produce mono/co-axial fibers.
Figure 2a: Typical setup for mono-axial electrospinning involves the use of a syringe pump to dispense a polymer solution through a needle gauge. A high voltage gradient is applied to the needle via a power supply and the formed fibers are accelerated towards the collecting ground (spinning wheel).
